how exactly do u bleed an abs unit? cuz im planning to unscrew the 6 plugs and take out the modual...plz help

 

the bleeder screw is on top of the modulator unit, looks just like a bleeder on a caliper
be careful though it is under pressure


Morgan - who knows it s under pressure from experience

 

Depends on what kind it is... He doesn't say what year. My '95 Integra has a bleed screw on the ABS unit, but my '98 Accord does NOT. The main brakes bleed thru that one. I don't remember what precautions you gotta take to remove it, but that may be different from year to year.

 

but when i take the module out, the exposing brake lines from the module, wont it be expsed to air? how do u bleed the brake lines that are connected to the module?

 

You gotta worry about 2 things, both depend on which ABS system comes in your car. Check a repair manual; I only know about '95 Integra or '98 Accord, & they're different from each other.

First, you have to remove the high pressure that's stored in your ABS module. Otherwise when you disconnect the first brake line it'll spray out with enough pressure to hurt you.

Then, when you take the module out, the lines will be open to air. After you replace the ABS unit, you have to bleed the brakes. IF your ABS unit has its own reservoir & bleed valve, you'll have to bleed that too. Otherwise, the main brakes bleed right through the ABS module.

On my '95 Integra, you bleed RR - LF - LR - RF - then ABS.
On my '98 Accord, you bleed LF - RF - RR - LR. The front brakes are first, because of the way the plumbing is hooked up. I suppose the order can be different for different years.
